Jen used
57 of her pink stickers and
27 of her gold stickers to decorate her diary. In the end, she had an equal number of pink stickers and gold stickers left. Given that Jen had a total of 98 pink and gold stickers at first, how many gold stickers did she use to decorate the diary?
|
Pink stickers |
Gold stickers |
Before |
7x5 = 35 u |
7x2 = 14 u |
Change |
- 5x5 = - 25 u |
- 2x2 = - 4 u |
After |
2x5 = 10 u |
5x2 = 10 u |
The number of pink stickers and gold stickers in the end is the same. Make the number of pink stickers and gold stickers in the end the same. LCM of 2 and 5 is 10.
Total number of stickers that Jen used to decorate the diary
= 35 u + 14 u
= 49 u
49 u = 98
1 u = 98 ÷ 49 = 2
Number of gold stickers that Jen used to decorate the diary
= 4 u
= 4 x 2
= 8
Answer(s): 8
